Biocytogen Signs RenMab™/RenLite™ Licensing Agreement with BeiGene

Biocytogen Signs RenMab™/RenLite™ Licensing Agreement with BeiGene

BEIJING, April 8, 2022 /PRNewswire/ -- Biocytogen Pharmaceuticals (Beijing) Co., Ltd. announced that they have reached an agreement with BeiGene (Beijing) Co., Ltd. ("BeiGene") (NASDAQ code: BGNE; Hong Kong Stock Exchange code: 06160; Shanghai Stock Exchange code: 688235) on March 10, for licensing of Biocytogen's fully human antibody RenMab™/RenLite™ mice platform with proprietary intellectual property rights of Biocytogen to develop fully human monoclonal antibodies, bispecific antibodies and other types of antibody drugs.

RenMab™ and RenLite™ was developed by Biocytogen over 5 years using SUPCE, a size-unlimited, precise chromosome engineering technology. In RenMab™ mice, the whole mouse variable regions of the heavy and kappa light chains were replaced by full human heavy chain VDJ segment and light chain VJ loci in situ; In RenLite™ mice, the whole mouse variable regions of the heavy chain were replaced with full human heavy chain VDJ segment in situ, and the whole mouse variable regions of the κ light chain was replaced with a single human κ light chain VJ loci in situ. RenMab™/RenLite™ mice can generate fully human antibody candidates with high affinity, specificity, and diversity for downstream antibody drug screening. Meanwhile, the common light chain antibodies generated by RenLite™ mice can greatly improve the efficiency of downstream assembly of complex drug molecules such as bispecific antibodies.

BeiGene is a global, science-driven biotechnology company focused on developing innovative and affordable medicines to improve treatment outcomes and access for patients worldwide. BeiGene currently has three approved medicines discovered and developed in our own labs: BTK inhibitor BRUKINSA in the United States, China, the EU and Great Britain, Canada, Australia and additional international markets; and the non-FC-gamma receptor binding anti-PD-1 antibody tislelizumab as well as the PARP inhibitor pamiparib in China. BeiGene has established a number of internal technology platforms, including small molecule drug development platform, proteolysis targeting chimera (CDAC) technology platform and bispecific (multispecific) antibody discovery platform, single B-cell antibody screening platform and antibody-drug conjugate (ADC) development platform.

For this collaboration, Dr. Yuelei Shen, Founder and CEO of Biocytogen, says "As one of the leading fully human antibody discovery platforms, Biocytogen's RenMab™/RenLite™ will provide strong support in drug development of challenging targets. Meanwhile, RenLite™ mice can generate bispecific antibodies with simple monoclonal antibody structures, reducing the difficulty of subsequent drug conjugation and opening more possibilities for innovative drug development."

Dr. Lai Wang, Senior Vice President and Global Head of R&D of BeiGene, says "BeiGene has always been focused on developing differentiated innovative drugs and the application of innovative technologies. It is hoped that licensing of RenMab™/RenLite™ mice platform will help us enrich the innovative drugs development path by exploring innovative targets and contribute to our vision of "Transform the biotechnology industry, creating impactful medicines that will be affordable and accessible to far more cancer patients around the world."
